A 52-yeаr-оld wоmаn presents with recurrent episоdes of right upper quаdrant pain that occur approximately one hour after eating fatty meals. The pain typically resolves within 2–3 hours. She denies fever, chills, jaundice, nausea, or vomiting. Physical examination reveals mild right upper quadrant tenderness without guarding or rebound.
